Rank the charge density at each labeled point a -e, greatest first. (note that point e indicates the left side of sphere 3; there is no labeled point on the right side of sphere 3.) rank positive charge greater than negative charge. include zero in your ranking. hint: image what would happen is sphere 1 were removed; then, consider what effect sphere 1 has on spheres 2 and 3 when it is present.

hèllo, sorry i really need some more points so if you need this qustion answered than retype it

f=ma newton's second law 7x8=56n

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
